Sembalun Trekking Route – Mount Rinjani Trekking Guide
The Sembalun Trekking Route is the most popular and widely used route to reach the summit of Mount Rinjani. Starting from Sembalun Village on the northeastern slope of the mountain, this route is known for its open savanna landscapes, long gradual ascents, and direct access to the summit trail.
Compared to the dense rainforest of the Senaru Route, Sembalun offers wide, open terrain with expansive views from the very beginning of the trek. This makes it the preferred starting point for summit programs and for trekkers who want a steady, less technical ascent before facing the steep summit push.

The Trekking Trail Experience
Savanna and Open Grassland
From the first steps, trekkers cross wide grasslands known as the Seven Hills (Tujuh Bukit). The trail gradually climbs across open terrain with constant views of surrounding valleys and hills. While the ascent feels steady and manageable, the exposure to sun and wind makes hydration and pacing essential.
Rest Stops Along the Sembalun Route
The route is divided into clearly marked posts:
- Pos 1 (1,300 m): First rest stop with open savanna views
- Pos 2 / Tengengean (1,500 m): Gradual ascent begins, overlooking the valley
- Pos 3 / Pos Balon (1,800 m): Named after a rock formation; common lunch stop
- Pos 4 (2,100 m): Final rest area before the steep climb to the rim
- Pelawangan Sembalun (2,639 m): Crater rim campsite with views of Segara Anak Lake, Mount Barujari, and the summit
From the crater rim, the summit trail is clearly visible rising sharply above the campsite.
